Answer:
Ivy initially put $ 650 in the account.
Step-by-step explanation:
Given that Ivy deposited some money into a savings account that earns 1% annual simple interest, and at the end of 5 years, she earned $ 32.50 in interest, to determine how much money did she put into the account initially, the following calculation must be performed:
32.50 / 5 = 6.5
1 = 6.5
100 = X
100 x 6.5 = X
650 = X
Therefore, Ivy initially put $ 650 in the account.
The answer should be D) 116.6 yards. To find the answer, you use Pythagoreans Theorem. Comment if you would like me to elaborate, please mark me brainliest it would be cash money of you
Answer:
588
Step-by-step explanation:
multiply length x width x height 7×6×14
In this case, since the standard deviation is known and
the sample size is less than 30, we will use the t-distribution. The formula
for calculating the confidence interval is:
Confidence Interval = X ± t * s / sqrt(n)
Where,
X = sample mean = $664.14
t = t score (taken from standard distribution tables)
s = standard deviation = $297.29
n = sample size = 14
At Degrees of Freedom = n – 1 = 13 and 98% Confidence
interval, z = 2.65
Substituting the values in the equation:
Confidence Interval = 664.14 ± 2.65 * 297.29 / sqrt(14)
Confidence Interval = 664.14 ± 210.55
Confidence Interval = 453.59 to 874.69
